Title: Rotor provided with permanent magnet and manufacture thereof
Inventor: OKUBO SHIGERU
IPC: H02K15/03
Filed: 1989-12-25
Abstract: PURPOSE:To increase design freedom of the profile at permanent magnet section by adhering permanent magnet powder onto a film having high permeability to produce a thin magnet band, which is then wound tubularly in order to form the permanent magnet section. CONSTITUTION:Top face 15a of a film 15 is applied with adhesive followed by adhesion of permanent magnet powder 16. It is then fed to a pressure roller 20 which applies pressure uniformly thus forming a film having uniform thickness. The film 15 is then fed to a second pressure roller 21 where it is subjected to pressure again. In the way, magnetic fields H1, H2 are applied for the purpose of demagnetization thus forming a thin band magnet 14. The thin band magnet 14 is then wound directly around a shaft 12 thus producing a permanent magnet section. The permanent magnet section is then placed, along with the shaft 12, in a heating furnace and heated thus sintering the permanent magnet powder 16.

Title: Wireless remote control device
Inventor: MUKAIKUBO JUNICHI
IPC: H04Q9/00
Filed: 1992-12-14
Abstract: PURPOSE:To improve operability and to achieve miniaturization and cost down. CONSTITUTION:When a push switch 54 is pushed first, a power source is turned on and an operation is started. In the case of setting a temperature, when the push switch 54 is kept pushed while the reference position 53a of a dial switch 53 is coincided with the measure of 'TEMP,' the value of the set temperature displayed on a display part 52 is cyclically changed 1 deg.C by 1 deg.C within the range of 17 deg.C-30 deg.C. In the case of stopping the operation, the push switch 54 is pushed only once while the reference position 53a is coincided with the measure of 'OFF.' Since only two switches are arranged on a control surface, the operation is facilitated and also the miniaturization and the cost down can be achieved.

Abstract: PURPOSE:To form an element on any face of a wafer by a method wherein an orientation flat is formed in a specific position on an element formation face which is projected inside the crystal face of the wafer so as to be parallel along its orientation. CONSTITUTION:The plane orientation 3 of an element formation face on an off-angle wafer 1 is tilted at a specific angle of about 4 deg. to the face orientation of 010 from the face orientation of 100. An orientation flat 2 is formed in such a way that the central point is situated in a position at 90 deg. or 270 deg. to the face orientation 3' when the face orientation 3 is projected on a crystal face along the face orientation of 100. When a wafer is reversed, the face orientation 3 on the rear is crystallographically equivalent to the face orientation 3 of the element formation face of 100; the positional relationship with the orientation flat 2 is not changed. Thereby, even when the surface and the rear of the wafer are mistaken, no trouble is caused and an element can be formed on any face.

Title: Running data display apparatus
Inventor: MUSA IKUO
IPC: G08G1/0968
Filed: 1990-11-29
Abstract: PURPOSE:To eliminate complicated manipulations by recognizing that a vehicle is returned to a specific starting point based on the data of the present position operated from the direction an the size of a direction vector and the distance sensor and the stopping time, and correcting the measuring error of a direction detector. CONSTITUTION:A vehicle starts from a point P0 to a point P1 separated at a distance l in the north direction. Then, the vehicle runs the distance l in the south direction to return to the staring point P0. At this time, the running locus operated by a running data display device is P0 P2 for the first run P0 P1, and P2 P3 for the returning run P1 P0. In other words, although the vehicle starts from the point P0 an returns to the point P0, the device calculates the current position as the point P2. Therefore, the calculating result of the current position is shifted by x=x3, y=y3. The detecting error of a direction detector is corrected by a vector P3P0/2l wherein P3P0 is a position correcting vector to correct the shift. Accordingly, the running information with improved reliability is displayed.

Abstract: PURPOSE:To decrease the number of parts of a lens actuator and also to miniaturize the actuator by using a Hall element as a displacement detecting means of an objective lens actuator and detecting the change of the magnetic flux pattern of a driving magnetic circuit. CONSTITUTION:The movable part of a lens actuator 2 includes a focus coil 6 and a track coil 7 and drives an objective lens 1 with an electromagnetic action attained with the function of a magnetic circuit 8.
